Vanadium Demand Explodes, page-2

I just read this last night in the book "Precision" about Henry Ford's early model cars I thought might interest a few.
"Given that the letter T is the twentieth letter, one might assume there were eighteen models made after the A; in fact, there were just five: the B (powerful, upscale, costly, with the engine at the front); the C (a fancier A, and like the A, with the engine beneath the seat); the F (a luxury A, sold only in green); the K (a luxury B, but with a six-cylinder engine, also under the hood); and finally, the N (cheap and light, using, for the first time, steel with added vanadium, an alloy that Henry Ford discovered in the wreckage of a crashed French racing car, and which he ordered used as extensively as possible in his future machines, as it gave the chassis added tensile strength and at a markedly lower weight)."
